Chaffinch

#Introduction Chaffinches are very abundant in Britain, it’s pattern helps it to blend into the environment when it is feeding on the ground (Slater and Ince 1979). The wingspan of a chaffinch is 24.5-28.5cm and the mass is 18-29 grams (Marler 1956). Males (see figure 1) and females (see figure 2) have different appearances.
